Need help again trying to understand what is going on in this tank before any one dies.
In the last thread I did about this tank, I had Yellow Neos dying, low PH, low GH, and unstable tap water. After advice, I went with 100% RO water using Salty Shrimp GH/KH, and did daily 10% water changes until the tank got to this:
Went back to weekly water changes and two weeks later, having problems again. I am doing water changes today and did some testing on the tanks.
The 7.5g is now:
RO water with Salty Shrimp (water change):
What could cause a drop in PH, GH, and KH?
Substrate is Eco Complete. I have one cholla wood in the tank and was about to put in an IAL. I do have moss that has gone completely brown on my driftwood. Could this cause that to happen?
I want this tank to match the remineralized RO and it doesn't seem like I can. Before the fix, 4 Yellow Neos died, many pond snails and lost 20 of my blue ramshorns.
